I dont really think thats a long term solution. Plus its very risky. Long queues are prime for atacks and large concentrations os angry, hungry people is just a bad idea.

You’ll need UN peace keepers around for some years. Palestinians dont really trust idf (understandable). And give back the control of gaza to the legitimate (well, the best we have now) palestinian authority. And start working on a two state solution with real pressure on both sides from the international comunity. Still, it will take decades (see the balkans)
